Ever-virgin Mary's "yes" was the beginning of our salvation

Today's Second Reading from the Office of Readings, more traditionally known as Matins, is a lesson for all Protestants and those Catholics who downplay, or disdain in the case of some, the Blessed Virgin Mary's role in our salvation. When one reads this sermon by St. Bernard one can readily see that our Salvation by Our Lord Jesus Christ was totally dependant on her yes. True, if she said no, God would have found someone else but it may have not happened even to now. I recall in the Blessed Anne Catherine Emmerich's writings that she asked her angel why it took so long for the Father to send His Son, the Messiah. She was told that it took 4000 years for a man and wife, Sts. Joachim and Anna, to be holy enough to bear Mary - the Immaculate Conception, who was conceived as all of us would have been had there been no Fall of our first parents, also something noted by Blessed Anne in her book, The Life of the Blessed Virgin Mary:

They embraced each other with holy joy, and each told the other their good tidings. They were in a state of ecstasy and enveloped in a cloud of light. I saw this light issuing from a great host of angels, who were carrying the appearance of a high shining tower and hovering above the heads of Anna and Joachim. The form of this tower was the same as I see in pictures, from the litany of the Blessed Virgin, of the Tower of David, the Tower of Ivory, and so forth. I saw that this tower seemed to disappear between Anna and Joachim, who were enveloped in a glory of brightness. I understood that, as a result of the grace here given, the conception of Mary was as pure as all conceptions would have been but for the Fall. I had at the same time an indescribable vision. The heavens opened above them, and I saw the joy of the Holy Trinity and of the angels, and their participation in the mysterious blessing here bestowed on Mary's parents. Anna and Joachim returned, praising God, to the exit under the Golden Gate; …

It was explained to me here that the Blessed Virgin was begotten by her parents in holy obedience and complete purity of heart, and that thereafter they lived together in continence in the greatest devoutness and fear of God. I was at the same time clearly instructed how immeasurably the holiness of children was encouraged by the purity, chastity, and continence of their parents and by their resistance to all unclean temptations; and how continence after conception preserves the fruit of the womb from many sinful impulses. In general, I was given an overflowing abundance of knowledge about the roots of deformity and sin.

Let us thank the Blessed Mother, for her, "be it done unto me according to thy word."

The whole world awaits Mary's reply     

You have heard, O Virgin, that you will conceive and bear a son; you have heard that it will not be by man but by the Holy Spirit. The angel awaits an answer; it is time for him to return to God who sent him. We too are waiting, O Lady, for your word of compassion; the sentence of condemnation weighs heavily upon us. 

The price of our salvation is offered to you. We shall be set free at once if you consent. In the eternal Word of God we all came to be, and behold, we die. In your brief response we are to be remade in order to be recalled to life.         

Tearful Adam with his sorrowing family begs this of you, O loving Virgin, in their exile from Paradise. Abraham begs it, David begs it. All the other holy patriarchs, your ancestors, ask it of you, as they dwell in the country of the shadow of death. This is what the whole earth waits for, prostrate at your feet. It is right in doing so, for on your word depends comfort for the wretched, ransom for the captive, freedom for the condemned, indeed, salvation for all the sons of Adam, the whole of your race.   

Answer quickly, O Virgin. Reply in haste to the angel, or rather through the angel to the Lord. Answer with a word, receive the Word of God. Speak your own word, conceive the divine Word. Breathe a passing word, embrace the eternal Word.   

Why do you delay, why are you afraid? Believe, give praise, and receive. Let humility be bold, let modesty be confident. This is no time for virginal simplicity to forget prudence. In this matter alone, O prudent Virgin, do not fear to be presumptuous. Though modest silence is pleasing, dutiful speech is now more necessary. Open your heart to faith, O blessed Virgin, your lips to praise, your womb to the Creator. See, the desired of all nations is at your door, knocking to enter. If he should pass by because of your delay, in sorrow you would begin to seek him afresh, the One whom your soul loves. Arise, hasten, open. Arise in faith, hasten in devotion, open in praise and thanksgiving. Behold the handmaid of the Lord, she says, be it done to me according to your word.

Responsory       

Virgin Mary, receive the word of the Lord brought to you by the angel: You will conceive and bear a son, both God and man. You will be called, Blessed among all women.

You will indeed bear a son, yet suffer no loss of virginity; you will be with child, yet remain a mother ever undefiled. You will be called, Blessed among all women.
